The ex-fiancé of slain U.S. Ambassador Chris Stevens, retired Navy SEAL and "Lone Survivor" Marcus Luttrell and four "Angel Moms" whose children were killed by undocumented immigrants will also be guests of Donald Trump's campaign at Wednesday's debate.
Lydie Denier was engaged to Stevens in 1995 though the couple never married. She recently published a book blaming Clinton for Stevens death, which she has been promoting on right-wing radio and blogs. Rep. Trey Gowdy, the chairman of the House Select Committee on Benghazi, attended a book signing, according to her Twitter account.
Stevens' family has said they do not blame former Secretary of State Hillary Clinton for the ambassador's 2012 death in Benghazi and have asked his passing not be politicized. "I feel a deep sorrow for the grief Chris's mother," Denier wrote in the book. "However, despite her wishes that Chris's name not be politicized, there is sadly, nothing she can do about this."

Trump Promises to Accept Election Results 'If I Win'
Donald Trump pledged on Thursday to "totally accept" the results of the 2016 election "if I win," further breaking with precedent in American politics.
"Ladies and gentlemen, I want to make a major announcement today," Trump said at a rally in Ohio. "I would like to promise and pledge to all of my voters and supporters and to all of the people of the United States that I will totally accept the results of this great and historic presidential election — if I win."
During the final debate on Wednesday, Trump refused to say if he will accept the outcome of the election, saying "I will keep you in suspense." Several prominent Republicans, including 2008 GOP nominee John McCain, have criticized Trump over the comment.
Trump called on Clinton to "resign from the race" over claims that she was given debate questions ahead of time.
Trump Claims Clinton 'Secretly Used' Debate Questions
Donald Trump accused Hillary Clinton of having advance notice of the debate questions, a claim for which he offered no evidence.
"Why didn't Hillary Clinton announce that she was inappropriately given the debate questions -- she secretly used them! Crooked Hillary," Trump tweeted Thursday morning.
Wednesday night's debate was more civil and policy-focused than previous match-ups, but Trump generated controversy by refusing to unequivocally accept the results on Election Day. "I will keep you in suspense," he said.
Why didn't Hillary Clinton announce that she was inappropriately given the debate questions - she secretly used them! Crooked Hillary.
Donald Trump's claim about a "rigged" presidential election was foreshadowed by a different contest he never won: an Emmy for the reality show he once hosted, "The Apprentice."
After rival Hillary Clinton at Wednesday's presidential debate brought up past tweets in which Trump said "politics" was to blame for not taking home a trophy, the Television Academy rejected any suggestions of collusion.
"Rest assured, the #Emmys are not rigged," the academy tweeted along with an infographic showing how nominations are made and ballots are cast.
Later, "Veep" star and Clinton supporter Julia Louis-Dreyfus (a seven-time Emmy winner!) followed up with her own tweet, emphatically saying the "Emmys are NOT rigged."
Harry Reid: Trump Must 'Reverse Course' on Election Results
Sen. Harry Reid joined a chorus of Republicans and Democrats condemning Donald Trump over his refusal to unequivocally accept the results of the election.
"Donald Trump's refusal to accept the results of the upcoming election is horrifying," Reid said in a statement. "He must immediately reverse course and state that he will accept the results of our free and fair elections. The statement must come from Trump's own lips. On an issue of this magnitude, statements from staff or surrogates will not suffice."
